More about this plugin
Monaco editor : VS Code engine + TypeScript language service; args typed from the parameter schema, env/sandbox globals declared, completions and diagnostics live. Editor and TS workers are bundled inline — the client bundle is a single file. - Durable store : tools live in the custom-tools settings namespace (schema defaults, composition base, user document — the ordinary settings layering). Edits apply live; restart restores them. - Live registration : enabled tools register into ctx.tools the moment the settings write commits; disabled/removed tools unregister immediately. The harness assembles tool schemas into the system prompt automatically. - Model self-service : custom tool create (upsert by name), custom tools list, and custom tool remove share the UI's validation gate and the ownership rules below.
